Definitions
- the present invention relates to a dust cover for a ball joint.
- the present invention also relates to a ball joint dust cover used for an automobile suspension device, a steering device, and the like.
- a ball joint dust cover shown in FIGS. 4 and 5 is known as a ball joint to which a dust cover is attached for the purpose of dust prevention and waterproofing of the ball joint joint.
- a ball head 200 formed at one end of the ball stud 100 is held in a socket 300.
- the shaft 400 at the other end of the ball stud 100 is fastened and fixed to the knuckle 500.
- one end large-diameter opening 90 of the rubber elastic material dust cover is fixedly held by a metal reinforcing ring 600 embedded in one end large-diameter opening 600 on the outer peripheral surface of the socket 300, and the other end small-diameter opening 70. Is configured to be held by the shaft portion 400.
- membrane part 800 which has connected the one end large diameter opening part 60 and the other end small diameter opening part 70 is exhibiting the drum shape which protruded outside.
- the reinforcing ring 600 includes a base portion 610 and a blade portion 620 extending from the base portion 610 toward the outer peripheral surface of the socket 300.
- the blade portion 620 bites into the outer peripheral surface of the socket 300, thereby preventing the dust cover from being detached from the socket 300. For this reason, the blade portion 620 needs to have spring elasticity.
- the base portion 610 has sufficient rigidity to prevent deformation when the large-diameter opening 60 is pushed into the socket 300 so that the sealing performance does not deteriorate. It is necessary to have.
- the seed metal material reinforcing ring 600 is manufactured by bending the outer peripheral side of an annular thin plate having a plate thickness Z. For this reason, the radial width A of the base 610 has inevitably increased. As a result, as shown in FIG. 4, the compression-side (left side in the drawing) film portion 800 interferes with the large-diameter opening 90 at one end, causing a problem that the film portion 800 is worn and damaged early.
- the base 610 can be pressed by the press-fitting jig P as shown in FIG.
- the radial width A of the base 610 is inevitably narrowed.
- the area where the base 610 can be pressed by the press-fitting jig P is reduced, and the problem that it is difficult to push the large-diameter opening 90 into the socket 300 is caused.
- an object of the present invention is to provide a dust cover for a ball joint that can be easily pushed into a large-diameter opening with a socket even if it has advanced.
- a ball head formed at one end of the ball stud is held in the socket, and a shaft portion at the other end of the ball stud is fastened and fixed to a knuckle.
- One end large-diameter opening embedded therein is fixedly held on the outer peripheral surface of the socket, and the other end small-diameter opening is held by the shaft portion, and the one end large-diameter opening and the other end small-diameter opening are connected.
- a concave portion is provided on the outer peripheral surface of the joint portion between the large-diameter opening and the film portion.
- the present invention has the following effects.
- the concave portion is provided on the outer peripheral surface of the joint portion between the large-diameter opening portion and the membrane portion, the reinforcement made of a metal material embedded in the large-diameter opening portion at one end. Even if the radial width of the base portion of the ring is reduced or the ball joint is made more compact, it is easy to push the large-diameter opening into the socket.
- the dust cover for a ball joint of the invention described in claim 2 since the plurality of recesses are provided in a uniform manner on the circumference, it is possible to prevent the film part from being deformed uniquely and The decrease in strength can be minimized.
- the outer diameter of the metal material reinforcing ring is particularly effective in the embodiment in which the outer diameter is equal to or smaller than the maximum outer diameter of the membrane portion. It is.
- the longitudinal section of the dust cover for ball joints concerning the present invention The principal part enlarged view of the dust cover for ball joints concerning this invention.
- the longitudinal section of the state where the jig for attaching the dust cover for ball joints concerning the present invention to a socket was attached.
- the principal part enlarged view of FIG. The longitudinal cross-sectional view of the state which attached the jig for attaching the dust cover for ball joints concerning a prior art to a socket.
- the aspect of the dust cover for ball joints according to the present invention is as follows.
- a ball head 2 formed at one end of the ball stud 1 is held in a socket 3, and a shaft portion 4 at the other end of the ball stud 1 is fastened and fixed to a knuckle 5, and a metal reinforcing ring 60 is embedded.
- One end large-diameter opening 6 is fixedly held on the outer peripheral surface of the socket 3, the other end small-diameter opening 7 is held on the shaft 4, and the one end large-diameter opening 6 and the other end small-diameter opening 7 are connected to each other.
- It has a configuration provided with a substantially drum-shaped film portion 8 protruding outward.
- a concave portion 91 is provided on the outer peripheral surface of the joint portion 9 between the large-diameter opening 6 and the film portion 8 at one end.
- the recess 91 it is difficult to mount by the conventional mounting jig P as shown in FIG. 6, and the base 61 of the metallic material reinforcing ring 60 embedded in the large-diameter opening 6 at one end is provided. Even if the radial width is narrow or the ball joint is compact, it is easy to push the large-diameter opening 6 into the socket 3 at one end.
- the concave portions 91 may be formed in an annular shape, but the embodiment in which a plurality of the concave portions 91 are provided on the circumference equally suppresses the specific deformation of the film portion 8 and minimizes the decrease in the strength of the film portion 8. Therefore, it is preferable.
- the radially inwardly projecting protrusions 10 and 10 provided at the tip of the split mounting jig J divided into a plurality of circles are provided.
- the mounting jig J is pushed (moved downward in the figure), so that the pressing force of the mounting jig J is passed through the projections 10, 10. It can be transmitted to the base 61 of the metal reinforcing ring 60.
- the aspect of the present invention in which the concave portion 91 is provided on the outer peripheral surface of the joint portion 9 between the large-diameter opening 6 and the film portion 8 is particularly effective.
- the reinforcing ring 60 can be applied in various forms manufactured by sheet metal processing, forging, or the like.
- the dust cover is formed of various rubber-like elastic materials.
- the reinforcing ring 60 can be made more compact without considering the mounting properties, the risk of the membrane portion 8 interfering with the large-diameter opening 6 on the compression side can be reduced.
- the present invention is not limited to the best mode for carrying out the invention described above, and various other configurations can be adopted without departing from the gist of the present invention.
